/t l This invention relates to improvements in spinning and twistingrings employed in the textile industry to support and/or guide atravelerv for revolving movement thereabout.

As is well known, the traveler moves around the'spinner or twister at arelatively high speed and the contacting surfaces, particularly those ofthe traveler, will readily wear away unless properly lubricated.Lubricant supplied to the ring should be uniformly distributed to thesurfaces thereof engaged by the traveler and should be confined to thering.

An object ofi thesinvention is the provision of a spinner or twisterring in which lubricant is uniformly supplied to all surfaces thereofengaged by the traveler; and to provide an assembly wherein such ring isso isolated from its support that lubricant supplied to the ring iseffectively confined thereto and cannot gain access to other portions ofthe assembly including the sup-` port.

,In carrying out the lubricant by capillary actionand to exude the sameat the surfaces of the ring; and there is provided a seal between thering and support which prevents the transmission of lubricanttherebetweenand serves as a means for mounting the ring on its support.The combined seal and mounting is impervious to lubricant, will notappreciably deteriorate in the presence thereof, and preferably shouldhave an inherent resiliency which will facilitate sealing engagement inresponse to a compressive force. More specically, the same may be formedfrom a material having the characteristics of rubber.

A.further object of the invention is the provision of a seal between thespinner or twister ring and its support which prevents the movement oflubricant therebetween and which also functions in conjunction with thering to provide an open reservoir with a part of the ring at the bottomof the latter adapted to receive lubricant.-

for transmission by capillary action'to those surfaces of the ringengaged by the traveler.

Other objects and advantages of the invention will be more apparent fromthe following description taken in connection with the accompanyingdrawings, in which:

Fig. 1 is a diammetrical section of a ring and rail assembly embodyingthe invention. f

. Fig. 2 is a top plan view of the ring shown in Fig. l. f

Referring to the drawings, a ring rail of a spinning or twisting frameas employed in the foregoing the spinner orV twister ring has a porositysumcien't to transmit 6 Claims. (Cl. 57-120) textile industry isindicated -by the numeral 6,

such rail having one or more openings therein for the reception of aring 6. The invention is appli- `cable to veither spinning or twistingrings and the s ame are hereinafter referred to in a generic sense as aspinner ring orrrings.

Each opening in the ring rail '5 includes a radially ,inwardly extendingflange 'I` and lis bounded by an annular axially extending wall 8, anannular radially extending wall 9 and a second annular axially extendingwail I0 at the free end of the flange 'I. The ring 6 includes a mainbody part I I and an annular'radially outwardly ex,-

.tending flange I2 disposed in overlapping relationship with the flange'I. While I have shownl the ring 6 mount d directly in the opening ofthe rail 5, nevertheessJ if desired the ring may be mounted in anadaptor or holder in the same manner as shown for the'direct mountingand such holder or adaptor may be bolted or otherwise secured to therail. The ring is thus supported directly from the rail or indirectlytherefrom when either adaptoror holder is used.

The ring `li guides a traveler I3 for relatively high speed revolvingmovement thereabout, the traveler being of the type which hooks over andengages the upper and lower edges of the ring 5.

.When employed as particularly illustrated the ring, serves to impart atwist to a plurality of strands I4, the twisted strands i5 being woundonto a' rotating spool i6. It is desirable to minimize the frictionbetween the traveler i3 and the surfaces of the ring 6 engaged therebyand for this purpose lubricant should be supplied to such surfaces inquantity sufficient to prevent frictional wear, especially'of thetraveler.

With the foregoing in mind, the ring 6 is preferably formed from a massof sintered metallic particles and has a degree of porosity sufficientto absorb lubricant and to transmit the same by capillary action. Ingeneral, the metallic particles are briquetted under relatively highpressure to produce a ring of substantially the desired shape anddimensions and the briquette is then sintered in a non-oxidizingatmosphere to cause the particles to adhere together and thus provide arelatively high strength porous body. The porosity may be varied byvarying the size and shape of the particles and by varying thebriquetting pressure. The ring may be hardened.

particularly at those surfaces thereof engaged by the traveler, by anywell known method or process, for example by nitriting.

While I prefer to-use ferrous metal particles. either alone or incombination with copper or tin particles, nevertheless other metals orcombinations thereof, such as copper and tin may be used. For example, amixture of 90 parts iron and parts copper or tin by weight is suitablefor the purpose intended or a mixture of 90 parts copper and 10 partstin by weight may be employed.

With the ring 6 as shown, lubricant may be supplied to the flange I2 andtransmitted therefrom by capillary action to the main body II, andparticularly the surfaces at the upper and lower edges thereof which areengaged by the traveler I3. In order to isolate the ring 6 and itslubricant content from the support, there is provided a seal, generallyindicated by the numeral Il, having a radial flange I8 extending betweenthe ring ilange I2 and the rail flange Il, and an axial flange I8extending between the outer peripheral edge of the ring flange I2 andthe rail wall 8. As shown the end face of the flange 1 is radiallyspaced from the main body II of the ring 6 to permit the traveler tomove therebetween and the seal flange I8 bridges such space and abutsthe outer periphery of the body Il above that portion of the latterwhich Is engaged by the traveler.

The flange I9 cooperates with that part of the main body II of the ringto form an annular lubricant reservoir, the bottom wall of which isprovided in part by the ring flange, A plurality of retainers '20, eachsecured to the ring rail 5 by a screw -2I, extend into this reservoirand engage the ring flange I2 to-press the latter flrmly against theseal flange I8. Lubricant can be dropped into this reservoir duringoperation of the mechanism and the seal will prevent leakage or drippageof the lubricant from the reservoir to the mechanism therebelow. Oilapplied at ,the flange I2 will be exuded at a relatively low rate to theperipheral surface of the main body of the ring,

In addition to functioning as a lubricant seal, the seal Il serves as ameans for resiliently mounting the ring 6 on its support and willminimize the transmission of vibrations therebetween which may bedeveloped by revolving movement of the traveler about the ring 6 andvertical reciprocal movement of the latter and the ring rail support 5.

Although but one specific embodiment of the invention has herein beenshown and described,

' it will be understood that various changes in the size, shape, andarrangement of parts may be made without departing from the spirit ofthe invention.
